For a good yawn I need to really open my mouth and push/strain my jaw muscles. If that doesnt happen, then the yawn feels incomplete to my body and it happens again and again till it works “right”
What is the reason/body function behind that?

I heard about this recently from a different article, but from my understanding, when we yawn, cerebrospinal fluid moves away from our brains. Cerebrospinal fluid “keeps the central nervous system running smoothly, delivering nutrients and removing waste.”
So, as a laymen, I think our brains are flushing the gunk out when we yawn. Having to yawn a second time, to me, would indicate that we didn’t get all the gunk out the first time.
